Via a processor, receiving a power off alert indicating a power off condition of a first processing system on which a first storage provider is installed, the first storage provider managing at least one storage controller. The method further can include, responsive to the power off alert, issuing a first command to a second storage provider installed on a second processing system, the first command indicating to the second storage provider to assume management of the storage controller.

Storage workload balancing in a data processing environment is provided by detecting automatically overloaded storage providers and automatically transferring storage subsystems from overloaded storage providers to storage providers with available capacity. This automatic workload balancing prevents some storage providers experiencing reduced performance while other available storage providers have unused excess capacity. If all of the available storage providers are overloaded, a new storage provider may be added automatically to a server and operating system instance that is best able to handle extra work.

Storage workload balancing

Storage scalability management is provided by adding storage in a data processing environment. A new storage subsystem is added automatically to an available storage provider only if doing so will not reduce the performance of the storage provider to an unacceptable level. If no such storage provider is available, a new storage provider is added automatically. The new storage provider is added automatically to the server and operating system that is best able to handle the additional work. Thus, a new storage subsystem is added automatically in a data processing environment in a manner that provides for system scalability while minimizing any adverse impact on system performance.
